Maceda vs. Macaraig, Jr.

The National Power Corporation (NPC) is exempt from both direct and indirect taxes pursuant to its amended charter, and the restoration of such exemptions by the Fiscal Incentives Review Board (FIRB) was a valid exercise of authority delegated by law.

The National Power Corporation (NPC) was created by Commonwealth Act No. 120 in 1936 to develop hydraulic power. Its charter and subsequent amendatory laws progressively granted it broad tax exemption privileges to enable it to fulfill its mandate of national electrification and to service its substantial domestic and foreign indebtedness. These exemptions became the subject of controversy when later laws, particularly P.D. No. 1177 (1977) and P.D. No. 1931 (1984), withdrew tax exemptions for all government-owned or controlled corporations (GOCCs). The FIRB later restored NPC's exemptions. Senator Ernesto Maceda challenged the validity of these restorations and the scope of NPC's exemption, specifically contesting claims for refund of indirect taxes on petroleum products.

• Nature of the Action: Petitioner, then a Senator, filed a petition for certiorari and prohibition seeking to declare illegal the tax exemptions and tax refund claims of the National Power Corporation (NPC).
• NPC's Legislative Tax Exemption History: NPC's charter (C.A. No. 120, as amended) and subsequent laws (R.A. Nos. 358, 6395; P.D. Nos. 380, 938) granted it broad exemptions to facilitate payment of its debts. P.D. No. 380 (1974) expressly exempted NPC from "all direct and indirect taxes" on petroleum products. P.D. No. 938 (1976) later amended Section 13 of R.A. No. 6395 to exempt NPC from "all forms of taxes, duties, fees, imposts..."
• Withdrawal and Restoration of Exemptions: P.D. No. 1177 (1977) withdrew tax exemptions for all GOCCs but allowed them to seek a subsidy. P.D. No. 1931 (1984) reiterated this withdrawal but empowered the FIRB to restore exemptions. The FIRB subsequently issued Resolutions Nos. 10-85 and 1-86 restoring NPC's exemptions. E.O. No. 93 (1986) again withdrew incentives but allowed restoration by the FIRB, which was done via Resolution No. 17-87.
• Specific Tax Refund Issue: The Bureau of Internal Revenue (BIR) issued a Tax Credit Memo to NPC for P58,020,110.79, representing specific and ad valorem taxes on bunker fuel oil purchased from oil companies during a period (Oct. 31, 1984 to April 27, 1985) when its exemption was retroactively restored. Petitioner challenged this refund.
• Oil Companies' Role: Private respondents Pilipinas Shell Petroleum Corporation and Caltex (Phils.), Inc., as suppliers, paid the indirect taxes to the BIR but passed the economic burden to NPC in the purchase price. The Court noted that E.O. No. 195 (1987) later reduced the ad valorem tax rate on bunker fuel oil to 0%.

• Repeal of Indirect Tax Exemption: Petitioner argued that P.D. No. 938, by using the phrase "all forms of taxes" without the explicit qualifier "directly or indirectly" found in P.D. No. 380, repealed NPC's indirect tax exemption.
• Invalid Restoration: Petitioner contended that P.D. No. 1177 had already abolished NPC's exemptions in 1977, leaving nothing for P.D. No. 1931 to withdraw or for the FIRB to restore. Thus, FIRB Resolutions Nos. 10-85 and 1-86 were issued without statutory authority.
• Illegal Tax Refund: Petitioner maintained that the Tax Credit Memo for P58 million was illegal because NPC did not possess indirect tax exemption privileges at the time the taxes were paid.

• Continuity of Exemption: Respondents countered that a chronological review of NPC laws showed a consistent legislative intent to grant comprehensive tax exemption. P.D. No. 938's "all forms of taxes" was a consolidation of prior exemptions, including indirect taxes.
• Valid FIRB Authority: Respondents argued that P.D. No. 1931 validly re-enacted the withdrawal provision of P.D. No. 1177 and established a new mechanism for restoration via the FIRB. The FIRB resolutions were therefore a valid restoration, not a creation, of exemptions.
• Due Process Not Violated: Respondents asserted that the approval of FIRB resolutions by the Minister of Finance, who was also FIRB Chairman, did not violate due process as no adverse private party was affected by the restoration of NPC's own privileges.

• Scope of Exemption: Whether P.D. No. 938 repealed NPC's exemption from indirect taxes.
• Validity of Withdrawal and Restoration: Whether P.D. No. 1177 and P.D. No. 1931 validly withdrew NPC's exemptions, and whether the FIRB validly restored them.
• Entitlement to Refund: Whether NPC was entitled to a tax refund for indirect taxes on petroleum products for the period in question.

• Scope of Exemption: P.D. No. 938 did not repeal NPC's indirect tax exemption. The phrase "all forms of taxes" was a consolidation and simplification of the previously enumerated exemptions in Section 13 of R.A. No. 6395, which included indirect taxes. The legislative history demonstrated a continuous intent to grant NPC comprehensive tax exemption to enable it to service its debts.
• Validity of Withdrawal and Restoration: P.D. No. 1177 validly withdrew NPC's exemptions, and P.D. No. 1931 validly reiterated this withdrawal. The FIRB, under the authority delegated by P.D. No. 1931 and E.O. No. 93, validly restored NPC's exemptions through Resolutions Nos. 10-85, 1-86, and 17-87. The approval of these resolutions by the Minister of Finance in his concurrent capacity as FIRB Chairman did not violate due process in this instance.
• Entitlement to Refund: NPC was entitled to the refund of the P58 million, as its exemption was retroactively restored to June 11, 1984, and the claim was filed within the prescriptive period under Section 230 of the National Internal Revenue Code. However, a separate, larger claim for P410 million was deemed time-barred.

• Statutes in Pari Materia — Statutes relating to the same subject matter (here, the NPC's charter and its amendments) must be construed together to ascertain legislative intent. The Court applied this principle to trace the evolution of NPC's tax exemption and concluded that P.D. No. 938's "all forms of taxes" encompassed both direct and indirect levies.
• Continuity of Legislative Policy in Revised Statutes — When a revised or consolidated act re-enacts provisions of prior acts in the same or substantially the same terms, the revision is taken as a continuation of the former law, preserving rights and liabilities thereunder. The Court used this to hold that P.D. No. 1931's withdrawal of exemptions was a continuation of P.D. No. 1177's policy.
• Delegation of Legislative Authority to Administrative Bodies — A delegating law is valid if it is complete in itself and sets forth the policy and standards to which the delegate must conform. E.O. No. 93, issued by President Aquino exercising legislative power, met this test by delegating to the FIRB the authority to restore tax exemptions based on specified considerations (e.g., national interest, revenue contribution).

• "It is crystal clear, therefore, that NPC had been granted tax exemption privileges for both direct and indirect taxes under P.D. No. 938." — This passage states the Court's definitive conclusion on the scope of NPC's exemption after analyzing the legislative history.
• "Tax exemptions are undoubtedly to be construed strictly but not so grudgingly as to ignore that many impositions taxpayers have to pay are in the nature of indirect taxes. To limit the exemption granted the National Power Corporation to direct taxes notwithstanding the general and broad language of the statute will be to thwart the legislative intention..." — This excerpt articulates the principle that strict construction of tax exemptions should not defeat the clear legislative purpose of a broad grant.
• "The oil companies which wish to sell to NPC absorb all or part of the economic burden of the taxes previously paid to BIR... This means also, on the other hand, that the NPC may refuse to pay the part of the 'normal' purchase price... which represents all or part of the taxes previously paid by the oil companies to BIR." — This explains the practical application of an indirect tax exemption in a commercial transaction.

• Pulido vs. Pablo, 117 SCRA 16 (1980) — Applied by analogy regarding the procedural rule that a defense or issue not seasonably raised is deemed waived. The Court used this to note that petitioner belatedly raised the effect of P.D. No. 1177.
• Zambales Chromite Mining Co. vs. Court of Appeals, 94 SCRA 261 (1974) and Anzaldo vs. Clave, 119 SCRA 353 (1982) — Cited and distinguished. These cases held that a reviewing official cannot review his own prior decision. The Court found them inapplicable to the FIRB's restoration of NPC's exemption, as no adverse private party's rights were involved.
• Pelaez vs. Auditor General, 15 SCRA 569 (1965) — Cited for the test of valid delegation of legislative power: the delegating statute must be complete in itself and fix a standard. The Court found E.O. No. 93 satisfied this test.

• Section 13, Republic Act No. 6395 (NPC Charter), as amended by P.D. No. 938 — The central provision exempting NPC from "all forms of taxes, duties, fees, imposts..." The Court interpreted this to include indirect taxes.
• Section 23, P.D. No. 1177 (Budget Reform Decree) — Withdrew tax exemptions of all GOCCs but allowed a subsidy mechanism. The Court held this validly withdrew NPC's exemptions.
• Sections 1 & 2, P.D. No. 1931 — Reiterated the withdrawal of exemptions and authorized the FIRB to restore them. The Court upheld the validity of this decree and the FIRB's authority thereunder.
• Section 230, National Internal Revenue Code of 1977 — Governs claims for refund of erroneously collected taxes. The Court applied its two-year prescriptive period to bar NPC's larger claim for P410 million.

Chief Justice Andres R. Narvasa, Justices Florentino P. Feliciano, Abdulwahid A. Bidin, Florenz D. Regalado, Flerida Ruth P. Romero, Jose A.R. Bellosillo, and Jose C. Melo concurred.
